Toul?, whom, it may concern:

Be it known that I, CHRISTOPHER W. LE- vALLEY, a citizen of the `United States, residing at Milwaulree, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in and Relating to Conveyers, of which the following is a speciiieation. i

My invei'itionrelates to endlesscarriers in which is employed a' single line of belting, usually sprocket-chain belting,- from which are suspended a series of swinging load-carriers, tie latter being mounted upon axes disposed substantially. arallel with the axes oi' articulation of the e ements of the endless carrier and arranged entirely to one. side of such carrier. An example of this type of eonveyer'is described and illustrated in my Patent No. 799,993, of September 19, 1905.

In the accompanying drawings, Figure 1 is an elevation of the upper part of a conveyer emplo Tinginy invention. Fig. 2 is an edge view thereof. Fig. 3 is a front view of one of the hangers or frames of the swinging carrier. Fig. 4 is an edge view of the part shown in Fig. 3. Figs. 5 and 6 are detail views ofthe carrier-engaging attachments applied to the steadying and guiding wheel.

In the accompanyinggdrawings, 2 represents the endless element of the conveyer,

which'is represented as being formed of articulated sprocket-links arranged to engage These arts may be of any ,usual construction, and I ave therefore deemed it unnecessary to show the lower supporting-wheel, around which the chain belt passes. The chain carries a series of package or articlesupports 4, mount-r ed upon. outwardly-projecting studs or pivotal pins 5. These latter are arranged to eX- tend outward from the side bars of certain of substantially parallel vwith the axes of the connecting-pin- This causes the carriers or supports for the loads-transported by the conveyor to be disposed entirely to one side of the chain, so that it may travel the entire circuit ofthe conveyer and past the face of the head-wheel, where the direction of the conveyer is changed without having its relation to' a horizontal plane disturbed.

' In operating with this type of conveyers it sometimes ha pens that vibration will be impartedy to the suspended load-carriers as they ass the head-wheel, and I have therefore dbvised a steadying-support and guide 3 and is mounted u on the chain, the 11p-moving line of chain en- I gaging with the wheel on one side and the down-moving line with it upon the'opposite side. The wheel 6 is thus -positively driven by the chain and its movements synchronlzed with those of the Wheel 3, which has also sprocket engagement with the chain.

Each support orl carrier 4 is provided with an arm 9, that is arranged to engage withv some part ofthe guiding-wheel 6 during the time the carrier or load-su port is making" the turn about the headli) that this arm 9 should depend centrally from eel 3. I prefer the lower cross-bar 10 of the frame of thecarrier or load -support and that its end should be somewhat offset and provided with a pin 11. `Thispin is adapted to engage with one ofthe forkedattachments 13, detailed in Figs. 5 and 6, applied to the guiding and steadying Wheel 6. y

14 designates a guide alongside the conveyer just below the head-wheel and in position to engage with the side of the hanger or carriera, which may be formed with a Wearing-surface 16 for such engagement, if this-be found desirable. The upper end of the guide extends inward toward the line of the chain orv belt 2, as indicated at 15, forming a sort of cam that operates to shift the passing carrier or load-support laterally to a slight extent inorder to cause a good engagement of the arm 9 with one of the forks 13, carried by the wheel 6.

As the wheels 3 and 6 travel with exactly l the same s eed,it follows that if the support or carrier ihr the load has engagement with each of them at corresponding points the carrier must be maintained in fixed relation to horizontal planes so long as such enga ement is maintained, and all ossibility of t e swinging of the carrier is eliminated. Such conditions are insured by the construction I have -illustrated and described. To insure the proper register and engagement of the erly come together without means for poslprojections carried'by the load-support, such as the arms 9, and the projections or parts of the Wheel that engage therewith, such as the :forks 13, the wheel 6 should be positively driven at the same speed as the Wheel 3, and this I secure Without an intervention of gearing, the presence of w 'ch is always ob- `jectionable when it can 'be dispensed with,

by providing the Wheel with teeth, sprockets, or other devices adaptin and positively driven tby thex chain or belt 2.

Itwill be understood that the use of the ide 14 15 is not essential to -my invention,

as the 'parts 9 and 13 will ordinarily proptively forcing them into engagement; but I prefer touse the guide, as it insures against around such Wheel, swinging carriers or supports for the loads conveyed arranged entirely to one side of the endless belt andconnected thereto, and a guide and steadying it to be directly devicefor the load-carriers as they pass the 35 head-wheel, an endless belt, load-carriers' suspended from thebeltand arranged en'- tirely to one side thereof, a guiding device with which the load-carriers are adapted to en age arranged adjacent to the head-wheel, an means for forcing the load-carriers into positive engagement With the said guiding device, substantially as set forth.

4. In a conveyer, the. combination of a head-wheel, an endless belt passing around the same, the carriers 4 suspended'from the chain and each provided with an arm 9,-a spocket-whee-l 6 situated below the head- Wheel and between the up and down moving lines'of the endless belt and arranged to engage therewith and be directly driventhereby, and the attachments 13 carried by the wheel 6 and arranged 'to Iengage with the arms 9 of the load-carriers as they ass the head-wheel, substantially asset fort CHRISTOPHER W. LEVALLEY.
